ISO 14271:2017 specifies the procedures for the hardness testing of etched cross-sections of resistance spot, projection, and seam welds. The aim of the hardness tests is to determine the Vickers hardness, in the low-force or microhardness range, of the weld nugget, the heat affected zone, and parent material in ferrous or non-ferrous metals for welds made in sheets of thickness 0,5 mm to 6 mm.
Abstract
Overview
ISO 14271:2017 defines standardized procedures for Vickers hardness testing (low‑force and microhardness) of etched cross‑sections from resistance spot, projection, and seam welds. The standard targets welds in ferrous and non‑ferrous sheets with thicknesses from 0.5 mm to 6 mm, and specifies how to locate and perform hardness traverses to determine hardness in the weld nugget, heat affected zone (HAZ), and parent material.
Key Topics
- Scope and purpose: Procedures for hardness testing of etched cross‑sections to obtain Vickers hardness (HV) in low‑force and microhardness ranges.
- Force ranges:
- Low‑force Vickers: defined between 1.961 N and 9.807 N; recommended test forces 1.961 N or 9.807 N for traverses.
- Microhardness: defined as forces **
